Hi all i just got my 175 re tuned by Alex at Alpha Jag in California. He sent me a laptop via post and he remotely uploaded my current tune then modified it and re flashed a few days later.
The car has a tune done in 2012, smaller upper pulley and a quicksilver sport exhaust…. Plenty of power to spare. Now after Alex re-tuned the car it not only runs incredibly smooth but pulls like a freight train
right up to red line. It is a lot more manageable yet much faster.. i now get that rush where the car accelerates so fast that it alters your visual perspective. Like tunnel vision mixed with g force.
i can see why his cars are breaking 1/4 mile records for Jags… one very happy customer!!!

 

I have had the Alpha Jag tune in my XKR for months now. No regrets.

 

Got my tune from AlphaJag a couple of months ago. Been unable to get to the track but Dragy says 11.96@122.07 with a pitiful 2.04 60ft.
This eve was 11.99@123.61 with an even more pitiful 2.17 60ft. 305 Supercar3 tires and it eats them alive in low.
I have an x pipe in place of front resonator, otherwise stock exhaust, an upper pulley and AJs tune. Stock intake.
The car weighs 4320 no driver and 1/2 tank of fuel. I weight 200+. So search any weight and trap speed calculator and see what it says for HP.

 

oh man that sounds awesome!I been thinking of getting this tune myself but im waiting a while cause my car still low mileage.But my question is how is the gas mileage with this tune?Did it get better or worst?

 

On my 2010 XFR, If I am on the interstate running 75-85 ish, I am getting 22+. Around town 18-20. Which is no different than what mine was on a stock tune. Of course if you want to "feel it" (and you will) that will go down accordingly. Pretty good considering that you can be driving across the continent on a trip, you can turn down the cd player, turn down the A/C, close the sunroof, and from your very comfortable seat bust out an 11 second run and touch supercar-ish top speeds given the right straight away........ then turn the A/C back to "Siberia" mode, turn up your favorite jams, open the sunroof and get some sun and air.....and smile for the next hundred miles.

 

normal driving is un affected and very smooth running . WOT is a different story. Obviously when you are pushing over 600HP you are going to burn a lot of fuel… but thats a trade off worth every penny. )) Im extremely happy with my tune.
